The AtmosphereAtmosphere are layers of gases that surrounds the Earth. 78% of the atmosphere is Nitrogen, 21% is Oxygen, and 1% is the water vapor and other gases. Air pressure is exerted in the atmosphere because the gravity cause the weight of the air. The air pressure increase as the altitude decrease and the air pressure decrease as the altitude increase.
There are five layers that make up the Earth's atmosphere. They are the troposphere, stratosphere, mesosphere, thermosphere, and the ionosphere. There is an ozone layer between the troposphere and the stratosphere. Each layer is explained below. |
Troposphere• Lowest layer
• Include almost all of the water vapor • About 12km in altitude • Temperature decreases as altitude increase |
Stratosphere• 12km to 50km
• Temperature increases as altitude increase |
Mesosphere• 50km to 80km
• Temperature decreases as altitude increase • Lorem ipsum dolor sit amet • Consectetur adipiscing elit |
Thermosphere• Outermost layer (80km to the space)
• Include almost all of the water vapor • Temperature increases rapidly as altitude increase |
Ionosphere• Region of charged particles (ions), overlapping the the lower thermosphere
•Lose electron when they absorb high energy wavelength solar radiation |
Ozone Layer• Located between troposphere and stratosphere
• Region of high ozone concentration • Composed of three oxygen atoms • Single oxygen atom collide with oxygen (O2)→O3 • Absorb UV rays and turn the energy into thermal energy |
